Description

Die Erfindung betrifft eine Schutzverbauung gemäß dem Oberbegriff des Anspruchs 1. Eine derartige Schutzverbauung ist aus der FR-A-2 673 253 bekannt.The invention relates to a protective structure according to the preamble of claim 1. Such a protective structure is from the FR-A-2 673 253 known.

Eine weitere Schutzverbauung ist aus der WO 2009/137951 bekannt. Diese bekannte Vorrichtung ist als Vorrichtung zur Stoßdämpfung von Seilkonstruktionen, insbesondere für Steinschlag-, Murgang- und Schneeverbauungen ausgebildet und absorbiert in ein auf Zug beanspruchtes Seil eingebrachte Energie dadurch, dass ein durch Zugkräfte deformierbares Zwischenstück, welches in das auf Zug beanspruchte Seil eingebaut ist, ein oder mehrere Längselemente aufweist. Hierbei steht das mindestens eine Längselement einerseits mit seinem einen Ende in Verbindung mit einem Seilende und andererseits wird es um ein mit einem anderen Seilende verbundenes Umlenkelement geführt. Schließlich sind Mittel vorgesehen, durch welche der gebildete Umlenkwinkel des oder der Längselemente bei der Belastung des Zwischenstücks im Wesentlichen aufrechterhalten bleibt.Another protective structure is from the WO 2009/137951 known. This known device is designed as a device for shock absorption of rope constructions, in particular for rockfall, debris flow and snow constructions, and absorbs energy introduced into a rope under tension by virtue of the fact that an intermediate piece deformable by tensile forces, which is installed in the rope under tension, has one or more longitudinal elements. Here, the at least one longitudinal element is connected on the one hand with its one end to a rope end and on the other hand it is guided around a deflection element connected to another rope end. Finally, means are provided by which the deflection angle formed of the longitudinal element or elements is essentially maintained when the intermediate piece is loaded.

Der Nachteil dieser bekannten Vorrichtung ist zunächst in einem relativ hohen baulichen Aufwand zu sehen, der vor allem darin begründet ist, dass zur Energieaufnahme eine Umbiegung bzw. Umlenkung des Zwischenstückes über das Umlenkelement erfolgt, wobei zur Aufrechterhaltung des Umlenkwinkels eine besondere Vorrichtung vorgesehen sein muss, die beispielsweise aus zwei Führungszapfen bestehen kann. Des Weiteren haben im Rahmen der Erfindung durchgeführte Untersuchungen ergeben, dass trotz des Zieles der gattungsgemäßen Druckschrift, den Stoß-Dämpfungsverlauf besser zu definieren bzw. zu optimieren hier weiterer Verbesserungsbedarf insbesondere beim Eintrag hoher Lasten in das Seil gegeben ist.The disadvantage of this known device is first of all to be seen in a relatively high level of structural complexity, which is primarily due to the fact that the intermediate piece is bent or deflected via the deflection element in order to absorb energy, a special device having to be provided to maintain the deflection angle, which can consist, for example, of two guide pins. Furthermore, investigations carried out within the scope of the invention have shown that, despite the aim of the generic document, to better define or optimize the shock absorption course, there is further need for improvement, in particular when high loads are introduced into the rope.

Aus der DE-A 31 08 607 ist eine Vorrichtung zur Zerstreuung und/oder Absorption von kinetischer Energie beschrieben, die aus einem Stapel von gitterförmigen Körpern besteht. Die gitterförmigen Körper sind gegeneinander versetzt stapelförmig angeordnet. Hierbei weist jeder Gitterkörper eine wabenförmige Grundstruktur auf, wobei die einzelnen Zellen hexagonalen Umriss aufweisen. Diese Zellen sind mit einem verformbaren Material, insbesondere mittels Polyurethanschaum ausgefüllt, und zwar so, dass der Schaum die Wände des gitterförmigen Körpers aussteift.From the DE-A 31 08 607 describes a device for dispersing and / or absorbing kinetic energy, which consists of a stack of lattice-shaped bodies. The lattice-shaped bodies are stacked in a staggered arrangement. Here, each lattice body has a honeycomb-shaped basic structure, the individual cells having a hexagonal outline. These cells are filled with a deformable material, in particular by means of polyurethane foam, in such a way that the foam stiffens the walls of the latticed body.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Schutzverbauung gemäß dem Oberbegriff des Anspruches 1 zu schaffen, bei der eine zumindestens weitgehend lineare Energieaufnahme der in das Seil eingebrachten Lasten gewährleistet ist.It is therefore an object of the present invention to provide a protective structure according to the preamble of claim 1, in which an at least largely linear energy absorption of the loads introduced into the rope is ensured.

Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruches 1. Die Unteransprüche haben vorteilhafte Weiterbildungen der Erfindung zum Inhalt.This object is achieved by the features of claim 1. The subclaims have advantageous developments of the invention.

Zu den Vorteilen der Erfindung zählt der Umstand, dass die bauliche Ausgestaltung der erfindungsgemäßen Vorrichtung einfacher ausgeführt werden kann, da beispielsweise keine Einrichtungen zur Aufrechterhaltung eines Umlenkwinkels erforderlich sind, da die Schneideinheit geradlinig und damit umlenkungsfrei durch das Bremsprofil hindurchgeführt bzw. vom Seil bei Aufbringung einer Zugkraft hindurchgezogen wird.The advantages of the invention include the fact that the structural design of the device according to the invention can be carried out more simply, since, for example, no devices for maintaining a deflection angle are required, since the cutting unit is guided in a straight line and thus without deflection through the brake profile or from the rope when applying a Traction is pulled through.

Die erfindungsgemäße Schutzverbauung kann gegen Steinschlag, Holzschlag, Lawinen oder Ähnlichem (wie z. B. auch als Fangzaun von Autorennstrecken), eingesetzt werden.The protective sheeting according to the invention can be used against stone chipping, logging, avalanches or the like (such as, for example, as a fence for car racing tracks).

Eine derartige Schutzverbauung weist üblicherweise eine Stützstruktur auf, die je nach Verbaulänge eine Mehrzahl beabstandeter, an einem Hang fixierbarer, Stützen umfasst. An den Stützen ist ein Netz, das vorzugsweise mit einer Geflechtsauflage versehen sein kann, befestigt. Hierfür ist ein oberes und ein unteres Tragseil vorgesehen. Das obere Tragseil führt das Netz im Bereich von Stützenköpfen der Stützen und das untere Tragseil führt das Netz im Bereich des Stützenfußes. Seitlich des Netzes sind die oberen und unteren Tragseile über Felsanker im Untergrund befestigt, wobei in diesem Bereich sowie vorzugsweise auch im Bereich des Netzes, die erfindungsgemäßen Energiedissipationsvorrichtungen vorgesehen sein können. Vom Prinzip her ist es auch möglich, als Stützstruktur nur ein Seil oder mehrere Seile zu verwenden, das bzw. die das Netz aufspannt/aufspannen.A protective structure of this type usually has a support structure which, depending on the installation length, comprises a plurality of spaced supports which can be fixed on a slope. A net, which can preferably be provided with a braid pad, is attached to the supports. An upper and a lower suspension cable are provided for this. The upper suspension cable guides the net in the area of the column heads of the supports and the lower suspension rope guides the net in the area of the column base. To the side of the net, the upper and lower suspension cables are fastened to the ground via rock anchors, the inventive ones in this area and preferably also in the area of the net Energy dissipation devices can be provided. In principle, it is also possible to use only one rope or several ropes as the support structure, which spans the net.

Bei einer besonders bevorzugten Ausführungsform sind zwischen dem oberen Tragseil und dem unteren Tragseil ein oder mehrere Mittelseile vorhanden, die mit dem Netz, beispielsweise durch ein Hindurchschlaufen, verbunden sein können. Die Verbindung kann hierbei über die gesamte Verbaulänge durchgängig erfolgen oder im Bereich des Verlaufes der Mittelseile über die Träger der Stützstruktur ausgelassen sein, wobei also dann die beispielhaft genannte Durchschlaufung in diesen Bereichen nicht erfolgt.In a particularly preferred embodiment, one or more middle ropes are present between the upper suspension rope and the lower suspension rope, which can be connected to the network, for example by looping through. The connection can be made continuously over the entire installation length or omitted in the area of the course of the middle ropes via the supports of the support structure, so that the looping mentioned by way of example does not then take place in these areas.

Die Mittelseile verlaufen über die gesamte Verbaulänge und werden ebenfalls seitlich der äußersten Träger der Schutzverbauung im Untergrund fixiert, wobei hier wiederum vorzugsweise Felsanker vorgesehen sein können, in deren Bereich Energiedissipationvorrichtungen bzw. Seilbremsen vorgesehen sein können, die entsprechend den Prinzipien vorliegender Erfindung ausgebildet sind.The middle cables run over the entire length of the installation and are also fixed to the side of the outermost support of the protective structure in the subsoil, here again rock anchors can preferably be provided, in the area of which energy dissipation devices or cable brakes can be provided which are designed in accordance with the principles of the present invention.

Stützstruktur auf, die in der Regel von einer Mehrzahl von Trägern gebildet wird, die beispielsweise über Felsanker 24 im Grund eines Hanges fixiert werden können. Je nach Verbaulänge der Schutzverbauung 23 sind eine Mehrzahl derartiger Träger vorgesehen, die in wählbaren Abständen zueinander nebeneinander am Hang H positioniert werden können. Vom Prinzip her ist es auch möglich, dass lediglich ein derartiger Träger oder nur eine Seilanordnung vorgesehen ist.The protective structure 23 has a so-called support structure, which is usually formed by a plurality of supports, which can be fixed, for example, via rock anchors 24 in the bottom of a slope. Depending on the length of the protective lining 23, a plurality of such supports are provided, which can be positioned next to one another on the slope H at selectable distances from one another. In principle, it is also possible that only such a carrier or only one cable arrangement is provided.

Diese Seilanordnung 29 kann ein oder mehrere Mittelseile aufweisen, die über Führungseinrichtungen 30 bzw. 31 am Träger 25 geführt sein können. Die Führungseinrichtungen 30 und 31 können hierbei beispielsweise als Schäkel, Rohrseilführungen oder Sattelführungen ausgebildet sein.In the illustrated, particularly preferred example, a middle rope arrangement 29 is provided between the upper suspension rope arrangement 27 and the lower suspension rope arrangement 28. This cable arrangement 29 can have one or more center cables, which can be guided on the carrier 25 via guide devices 30 or 31. The guide devices 30 and 31 can be designed, for example, as shackles, tubular rope guides or saddle guides.

Ferner verdeutlicht die Ausführungsform der Schutzverbauung 23 gemäß Fig. 1, dass ein oberes Abspannseil 32 und ein unteres Abspannseil 33 vorgesehen sind. Das obere Abspannseil 32 hält den Stützenkopf der Stütze 25 über eine Befestigungseinrichtung 34 (Felsanker) im Untergrund des Hanges H, während diese Fixierung das untere Abspannseil 33 im unteren Bereich (Stützenfuß 26) der Stütze 25 übernimmt. Wie Fig. 1 verdeutlicht, kann in jeder dieser Abspannseilanordnungen 32, 33 ein Bremselement bzw. eine Energiedissipationsvorrichtung eingeschaltet sein, die in Fig. 1 durch den Block 35 symbolisiert ist und die gemäß den zuvor erläuterten Ausführungsformen der erfindungsgemäßen der erfindungsgemäßen Dissipationsvorrichtung ausgebildet sein kann.The embodiment of the protective lining 23 according to FIG Fig. 1 that an upper guy cable 32 and a lower guy cable 33 are provided. The upper guy cable 32 holds the support head of the support 25 via a fastening device 34 (rock anchor) in the subsoil of the slope H, while this fixation takes over the lower guy cable 33 in the lower region (support foot 26) of the support 25. How Fig. 1 illustrates, a braking element or an energy dissipation device can be switched on in each of these guy cable arrangements 32, 33 Fig. 1 is symbolized by block 35 and which can be designed according to the previously explained embodiments of the inventive dissipation device.

Eine entsprechende Fixierung der oberen und unteren Tragseile (die in Fig. 1 nicht dargestellt ist) sowie der Mittelseile, kann über eine Energiedissipationsvorrichtung 36 (auch Energieabsorbierungsstruktur oder Seilbremse genannt) erfolgen, die ebenfalls entsprechend den Prinzipien der vorliegenden Erfindung, die nachfolgend anhand der Fig. 2 bis 6 erläutert werden, ausgebildet sein kann. Hierbei ist es möglich, in jedes der einzelnen Seile 27, 28, 29, 32 bzw. 33 eine Dissipationsvorrichtung 1 einzuschalten, oder mehrere Seile (wie z.B. die Seile 29 und 32, 33) einer derartigen Dissipationsvorrichtung 1 zuzuordnen.A corresponding fixation of the upper and lower suspension cables (which in Fig. 1 not shown) as well as the middle ropes, can take place via an energy dissipation device 36 (also called energy absorption structure or rope brake), which likewise corresponds to the principles of the present invention, which are described below with reference to FIG 2 to 6 can be explained. It is possible to switch on a dissipation device 1 in each of the individual ropes 27, 28, 29, 32 or 33, or to assign several ropes (such as ropes 29 and 32, 33) to such a dissipation device 1.

In den Fig. 2 und 3 ist eine erste besonders bevorzugte Ausführungsform einer erfindungsgemäßen Vorrichtung 1 zur Energiedissipation (Energiedissipationsvorrichtung) dargestellt.In the 2 and 3 A first particularly preferred embodiment of a device 1 for energy dissipation (energy dissipation device) is shown.

Die Vorrichtung 1 weist ein Bremsprofil 2 auf, das im Beispielsfalle aus einem langgestreckten rechteckigen Blechstreifen 11A und einem daran mittig angeschweißten Führungssteg 11B aufgebaut ist, an dem an einem Ende ein Endanschlag 10 fixiert ist.The device 1 has a brake profile 2, which in the example is composed of an elongated rectangular sheet metal strip 11A and a guide web 11B welded to it in the center, to which an end stop 10 is fixed at one end.

Wie eine Zusammenschau der Fig. 2 und 3 verdeutlicht, ist an dem dem Endanschlag 10 gegenüberliegenden Ende des Blechstreifens 11A in diesem ein Paar vorgeschnittener Spalte zum Einsetzen von Schneidblechen 5A und 5B vorgesehen, die Teile einer Schneideinheit 3 sind, die mit dem Bremsprofil 2 zur Erzeugung der Energiedissipation zusammenwirkt. Die vorgeschnittenen Spalte 7A, 7B zum Einsetzen dieser Schneidbleche 5A und 5B gehen in spitz zulaufende Einlaufbereiche 8A bzw. 8B über, die wiederum in vorgeschnittene, die gesamte Blechstärke des Blechstreifens 11A durchgreifende Einführschlitze 9A und 9B übergehen.Like a synopsis of 2 and 3 2, a pair of pre-cut gaps for inserting cutting plates 5A and 5B, which are parts of a cutting unit 3 which cooperates with the brake profile 2 for generating the energy dissipation, is provided in the end of the sheet metal strip 11A opposite the end stop 10. The pre-cut gaps 7A, 7B for inserting these cutting plates 5A and 5B merge into tapering inlet areas 8A and 8B, which in turn merge into pre-cut insertion slots 9A and 9B which penetrate the entire sheet thickness of the sheet metal strip 11A.

Wie sich insbesondere aus der Fig. 3 ergibt, weist das Schneidblech 5A eine Schneidkante 4A auf, wie auch das Schneidblech 5B eine derartige Schneidkante umfasst, die nachfolgend unter Bezugnahme auf die Fig. 6 im Einzelnen erläutert werden wird.As can be seen in particular from the Fig. 3 results, the cutting plate 5A has a cutting edge 4A, just as the cutting plate 5B also comprises such a cutting edge, which is described below with reference to FIG Fig. 6 will be explained in detail.

Wie die Zusammenschau der Fig. 2 und 3 ferner zeigt, ist der Blechstreifen 11A mit einer Anschlusslasche 12 für ein in den Fig. 2 und 3 nicht dargestelltes Seil versehen, wozu diese Anschlusslasche 12 eine Anschlussausnehmung 14 umfasst, in die z.B. ein Seilschäkel eingehängt werden kann.Like the synopsis of 2 and 3 further shows, the sheet metal strip 11A with a connecting tab 12 for one in the 2 and 3 provided rope, not shown, for which this connecting tab 12 comprises a connection recess 14, in which, for example, a rope shackle can be hung.

Die Schneideinheit 3 weist ebenfalls eine Anschlusslasche auf, die mit der Bezugsziffer 13 gekennzeichnet ist und in der ebenfalls eine Anschlussausnehmung 15 vorgesehen ist, in die wiederum z.B. ein Schäkel einer Seilanordnung eingehängt werden kann.The cutting unit 3 also has a connection lug, which is identified by the reference number 13 and in which a connection recess 15 is likewise provided, in which, for example, a shackle of a rope arrangement can be attached.

Fig. 3 verdeutlicht hierbei, dass die Anschlussausnehmungen 14 und 15 in einer Fluchtlinie F liegen, um beim Hindurchziehen der Schneideinheit 3 durch das Bremsprofil 2 keine Verkantungen hervorzurufen, um den Schneidvorgang zu vergleichmäßigen. Fig. 3 makes it clear that the connection recesses 14 and 15 lie in an alignment line F, so that when the cutting unit 3 is pulled through the brake profile 2, no canting occurs in order to make the cutting process more uniform.

Eine derartige Vorrichtung 1 zur Energiedissipation kann in die Schutzverbauung 23 eingebaut werden, beispielsweise an der Stelle der dort mit den Bezugsziffern 35 und 36 gekennzeichneten Vorrichtungen zur Energiedissipation.Such a device 1 for energy dissipation can be installed in the protective structure 23, for example at the location of the devices for energy dissipation identified there with the reference numbers 35 and 36.

Der besondere Vorteil der Ausführungsform gemäß den Fig. 2 und 3 ist darin zu sehen, dass auf sehr einfache Art und Weise durch eine entsprechende Dimensionierung des Blechstreifens 11A die aufzunehmende Energie eingestellt werden kann.The particular advantage of the embodiment according to the 2 and 3 can be seen in the fact that the energy to be absorbed can be adjusted in a very simple manner by appropriately dimensioning the metal strip 11A.

Ferner ergeben sich Vorteile hinsichtlich einer einfachen Montage durch die vorgeschnittenen Spalte 7A und 7B, in die die Schneidbleche 5A und 5B auf einfache Art und Weise eingesetzt werden können. Ferner wird der Schneidvorgang durch die sich an die Spalte 7A und 7B anschließenden spitz zulaufenden Einlaufbereiche 8A und 8B sowie die sich daran wiederum anschließenden Einführschlitze 9A und 9B verbessert.Furthermore, there are advantages with regard to simple assembly by means of the pre-cut gaps 7A and 7B, in which the cutting plates 5A and 5B can be inserted in a simple manner. Furthermore, the cutting process is improved by the tapering inlet areas 8A and 8B adjoining the gaps 7A and 7B, and the insertion slots 9A and 9B, which in turn adjoin them.

Bei der Ausführungsform gemäß den Fig. 2 und 3 ist das Bremsprofil 2, wie zuvor erläutert, durch den flachen Blechstreifen 11A und den Führungssteg 11B aufgebaut, bildet also ein T-Profil. Der Führungssteg 11B ist hierbei eine Option, der zwar die Führung der Schneidbleche 5A und 5B verbessert, jedoch nicht unbedingt vorgesehen sein muss, so dass das Bremsprofil 2 erfindungsgemäß auch ein flacher bzw. ebener Blechstreifen wie der Blechstreifen 11A sein kann.In the embodiment according to the 2 and 3 If, as previously explained, the brake profile 2 is constructed by the flat sheet metal strip 11A and the guide web 11B, it thus forms a T-profile. The guide web 11B is an option here which, although it improves the guidance of the cutting plates 5A and 5B, does not necessarily have to be provided, so that the brake profile 2 according to the invention can also be a flat or flat sheet metal strip like the sheet metal strip 11A.

Beim Hindurchziehen der Schneideinheit 3 mit ihrer Schneide bzw. ihren Schneiden 4A, 4B durch das Bremsprofil wird die Energiedissipation dadurch bewirkt, dass das Bremsprofil 2 durch die Schneide bzw. die Schneiden 4A, 4B gespalten wird, also ein Teil des Bremsprofils 2 durch die Schneideinheit 3 abgetrennt wird.When the cutting unit 3 with its cutting edge or its cutting edges 4A, 4B is pulled through the braking profile, the energy dissipation is brought about by the braking profile 2 being split by the cutting edge or the cutting edges 4A, 4B, that is to say a part of the braking profile 2 by the cutting unit 3 is separated.

Im Gegensatz hierzu verwendet die nicht zur Erfindung gehörende Ausführungsform der Vorrichtung 1 zur Energiedissipation gemäß den Fig. 4 und 5 ein Hohlprofil als Bremsprofil 2, das beispielsweise rund oder eckig im Querschnitt ausgebildet sein kann. Mit anderen Worten ist jedwede Art von Hohlprofil für die Ausführungsform gemäß den Fig. 4 und 5 geeignet.In contrast to this, the embodiment of the device 1 for energy dissipation according to FIGS 4 and 5 a hollow profile as a brake profile 2, which can be round or angular in cross section, for example. In other words, any type of hollow profile for the embodiment according to the 4 and 5 suitable.

Die Schneideinheit 3 der Ausführungsform gemäß den Fig. 4 und 5 weist ein Schneidblech 17 mit Schneidkanten 4A und 4B auf, wobei das Schneidblech 17 an einem Zugstab 16 fixiert ist, der in das hohle Bremsprofil 2 eingesetzt werden kann, wie dies die Fig. 4 und 5 verdeutlichen. An seinem freien Ende weist der Zugstab 16 eine Anschlusslasche 13 mit einer Anschlussausnehmung 15 auf, in die ein Seilschäkel eines Seiles einer Schutzverbauung eingehängt werden kann.The cutting unit 3 of the embodiment according to the 4 and 5 has a cutting plate 17 with cutting edges 4A and 4B, the cutting plate 17 being fixed to a pull rod 16 which can be inserted into the hollow brake profile 2, as shown in FIG 4 and 5 clarify. At its free end, the tension rod 16 has a connecting lug 13 with a connecting recess 15, into which a rope shackle of a rope of a protective structure can be hung.

Das Bremsprofil 2 weist am gegenüberliegenden Ende ebenfalls eine Anschlusslasche auf, die mit der Bezugsziffer 12 gekennzeichnet ist, da sie der Anschlusslasche 12 der Ausführungsform gemäß den Fig. 2 und 3 entspricht und dementsprechend eine Anschlussausnehmung 14 wiederum für das Einhängen eines Seilschäkels aufweist.At the opposite end, the brake profile 2 also has a connecting lug, which is identified by the reference number 12, since it connects the connecting lug 12 of the embodiment according to FIGS 2 and 3 corresponds and accordingly has a connection recess 14 in turn for hanging a rope shackle.

Wird bei einem Bremsvorgang der Zugstab 16 mit dem daran fixierten Schneidblech 17 mit seinen Schneidkanten 4A und 4B durch das hohle Bremsprofil 2 hindurchgezogen, schneiden die Schneidkanten 4A und 4B das Bremsprofil auf, wodurch es zur Energiedissipation kommt. Das Schneidprofil 17 ist hierbei als Flachprofil ausgebildet, wie sich dies aus einer Zusammenschau der Fig. 4 und 5 ergibt.If the pull rod 16 with the cutting plate 17 fixed thereon with its cutting edges 4A and 4B is pulled through the hollow braking profile 2 during a braking operation, the cutting edges 4A and 4B cut the braking profile open, as a result of which energy dissipation occurs. The cutting profile 17 is designed as a flat profile, as can be seen from a synopsis of the 4 and 5 results.

Wie die perspektivische Darstellung der Schneideinheit 3 in Fig. 6 verdeutlicht, sind die Schneidbleche bzw. Schneidplatten 5A und 5B im Beispielsfalle in einem oberen Bereich trapezförmig ausgebildet und parallel zueinander ausgerichtet. Ferner weisen die Schneidplatten 5A und 5B Befestigungsplatten 19 und 20 auf, die mit den trapezförmigen Bereichen einstückig ausgebildet sind und die mit der Anschlusslasche 13 verbunden, vorzugsweise verschweißt, werden, was den Endmontagezustand der erfindungsgemäßen Schneideinheit 3 darstellt.As the perspective view of the cutting unit 3 in Fig. 6 clarified, the cutting plates or cutting plates 5A and 5B in the example are formed trapezoidal in an upper region and aligned parallel to each other. Furthermore, the cutting plates 5A and 5B have fastening plates 19 and 20 which are formed in one piece with the trapezoidal regions and which are connected, preferably welded, to the connecting lug 13, which represents the final assembly state of the cutting unit 3 according to the invention.

Wie Fig. 6 verdeutlicht, nehmen die Schneidbleche bzw. Schneidplatten 5A und 5B einen wählbaren Abstand A zueinander ein, da im auf das Bremsprofil 2 aufgesetzten Zustand in dem entstehenden Zwischenraum, falls vorgesehen, der Führungssteg 11B aufgenommen wird.How Fig. 6 makes clear, the cutting plates or cutting plates 5A and 5B are at a selectable distance A from one another, since in the state placed on the brake profile 2, the guide web 11B is accommodated in the resulting space, if provided.

Ferner verdeutlicht Fig. 6, dass zwischen den trapezförmigen Abschnitten der Schneidplatten 5A und 5B und den Befestigungsplatten 19 und 20 jeweils ein Einführschlitz 17 bzw. 18 vorgesehen ist, der in etwa U-förmig ausgebildet ist und in dessen Grund jeweils die Schneidkante 4A bzw. 4B angeordnet ist. Wie anhand der Schneidkante 4B ersichtlich, läuft diese in eine Führungsschräge 4C aus, die an einer Außenwandfläche 6C der Schneidplatte 5B endet. Eine dementsprechende Schräge ist auch bei der Schneidkante 4A vorgesehen, in Fig. 6 jedoch nicht sichtbar. Diese Schrägen erleichtern beim Einschneiden in das Bremsprofil 2 das Abscheren des abgetrennten Profilbereiches und ergeben daher eine vergleichmäßigte Energiedissipation.Also clarified Fig. 6 that between the trapezoidal sections of the cutting plates 5A and 5B and the fastening plates 19 and 20 there is an insertion slot 17 and 18, respectively, which is approximately U-shaped and in whose base the cutting edge 4A and 4B is arranged. As can be seen from the cutting edge 4B, this ends in a guide bevel 4C which ends on an outer wall surface 6C of the cutting plate 5B. A corresponding slope is also provided for the cutting edge 4A, in Fig. 6 however not visible. These bevels make it easier to cut off the separated profile area when cutting into the brake profile 2 and therefore result in a more uniform energy dissipation.

Ferner verdeutlicht Fig. 6, dass beide Schneidplatten 5A und 5B zugeordnete Aufnahmeöffnungen 6A und 6B aufweisen, die fluchtend zueinander angeordnet sind, so dass Verbindungselemente, wie zum Beispiel eine Verbindungsschraube mit zugeordneter Mutter durch diese Aufnahmeöffnungen 6A und 6B gesteckt werden kann und mit entsprechenden Muttern fixiert werden kann. Diese Verbindungsschraube, die in Fig. 6 nicht im Einzelnen gezeigt ist, verbessert die Führung der Schneidbleche bzw. Schneidplatten 5A und 5B beim Schneidvorgang, so dass sichergestellt ist, dass die Schneidplatten 5A und 5B beim Schneidvorgang bzw. Spaltvorgang nicht nach außen weggeschert werden.Also clarified Fig. 6 that both cutting plates 5A and 5B have associated receiving openings 6A and 6B, which are arranged in alignment with one another, so that connecting elements, for example a connecting screw with an associated nut, can be inserted through these receiving openings 6A and 6B and can be fixed with corresponding nuts. This connecting screw, which in Fig. 6 is not shown in detail, improves the guidance of the cutting plates or cutting plates 5A and 5B during the cutting process, so that it is ensured that the cutting plates 5A and 5B are not sheared outwards during the cutting process or splitting process.

Wie sich aus der voranstehenden Erläuterung der Komponenten der erfindungsgemäßen Dissipationsvorrichtung 1 ergibt, stellen sowohl das Bremsprofil 2 wie auch die Schneideinheit 3 jeweils selbständig und voneinander unabhängig handelbare Objekte und damit Erfindungsmerkmale dar, die durch die zuvor erläuterten Konstruktions- und Funktionsmerkmale gekennzeichnet sind.As can be seen from the above explanation of the components of the dissipation device 1 according to the invention, both the brake profile 2 and the cutting unit 3 each represent objects which can be traded independently and independently of one another and thus features of the invention which are characterized by the construction and functional features explained above.

Ferner ist hervorzuheben, dass bei beiden zuvor beschriebenen Ausführungsformen die Schneiden bzw. Schneidkanten 4A, 4B gehärtet sein können. Eine derartige Härtung kann bevorzugterweise durch eine Gasnitrierung erfolgen.It should also be emphasized that in both of the previously described embodiments, the cutting edges 4A, 4B can be hardened. Such hardening can preferably be carried out by gas nitriding.

Die zuvor beschriebene besonders bevorzugte Ausführungsform des Bremsprofils 2 für die Vorrichtung 1 zur Energiedissipation kann auch lediglich als flacher Blechstreifen ausgeführt sein, der weder vorgeschnittene Einsteckspalte 7A, 7B noch Einlaufbereiche 8A, 8B oder Einführschlitze 9A, 9B aufweist. Lediglich das Vorsehen von Anschlusslaschen, wie der beispielhaft beschriebenen Anschlusslaschen 12, 13 ist in diesem Falle nötig. Die zuvor beschriebene Ausführungsform des Bremsprofils 2 mit Einsteckspalten, Einlaufbereichen und Einführschlitzen ist jedoch eine besonders bevorzugte Ausführungsform. Die Einlaufbereiche 8A, 8B können hierbei sowohl spitz als auch stumpf zulaufend ausgebildet sein. Unter "spitz zulaufend" ist hierbei zu verstehen, dass ein Zulaufbereich, wie bei einem spitzen Winkel, geschaffen wird, während "stumpf zulaufend" bedeuten würde, dass der Zulaufbereich zumindest leicht gerundet ausgebildet sein kann.The previously described particularly preferred embodiment of the brake profile 2 for the device 1 for energy dissipation can also be implemented only as a flat sheet metal strip which has neither pre-cut insertion gaps 7A, 7B nor inlet areas 8A, 8B or insertion slots 9A, 9B. Only the provision of connection lugs, such as the connection lugs 12, 13 described by way of example, is necessary in this case. However, the previously described embodiment of the brake profile 2 with insertion gaps, inlet areas and insertion slots is a particularly preferred embodiment. The inlet areas 8A, 8B can be designed to be either pointed or blunt. “Tapering” is to be understood here to mean that an inflow area, such as at an acute angle, is created, while “tapering” would mean that the inflow area can be at least slightly rounded.

Neben der voranstehenden schriftlichen Offenbarung wird hiermit explizit zur Ergänzung der Erfindungsoffenbarung auf die zeichnerische Darstellung der Erfindung in den Fig. 1 bis 6 Bezug genommen.In addition to the above written disclosure is hereby explicitly to supplement the disclosure of the invention to the graphic representation of the invention in the 1 to 6 Referred.
